5.1 CEREC Radio Device Network Overview

The network units in the CEREC Radio Device network create a so called peer-to-peer
mesh network. This means that there is not a master or slave as with Bluetooth or a
central controlling access point as with Wi-Fi.
As such there is no distinction between a network unit connected to a milling unit, one
that is built into an acquisition unit or one that is connected to a LAN infrastructure: any
network unit belonging to the same network (see "Create a network") can communicate
which each other as soon as they are in each other's range. This is also applicable when
they are out of range of all other network units making the network connections very
flexible.
This wireless network operates in the 2.4GHz band which is available worldwide for
license-free operation. It therefore needs to be able to operate in coexistence with other
wireless networks such as Wi-Fi or Bluetooth. The network accomplishes this by avoiding
congested channels when possible. However, the network is not immune to interferences
caused by these other wireless technologies. The result of these interferences can be a
reduced range or lower performance. The network technology therefore offers several
easy mechanisms by which a network can be extended to achieve better coverage (see
"Extending the network").
The network can also easily be extended and the coverage increased, using LAN cables
or even an existing LAN infrastructure (see "Increasing network coverage").
